We had a mother (R1R1 K-neg) from Tamil Nadu who had several visits to our hospital. Anti-H lectin was negative. Here is a summary of her workup:
Mother’s ABO/D Typing:
Mother’s Antibody Screen:
Mother’s Antibody Identification:
She gave birth to a baby girl, group B, R1R1 K-neg. This is the neonate’s workup:
Despite the weakly positive IgG DAT, the eluate was negative. The neonate was asymptomatic.
Anti-H is mainly an IgM antibody and does not cross the placenta, thus no HDFN was noted.
